K, so you didn't understand what Fauscoval just said. There is no empirical way to prove this point. For all we know, any reduction in cases with serious symptoms could be thanks to everyone having been exposed to the actual virus, and therefore natural immunity has kicked in.
There is also the fact that the first number of waves took out the most vulnerable among us, leaving those who are better able to deal with Covid.
Given that the Pfizer CEO outright stated that the first couple of shots were effectively useless, means that they don't even "lesson symptoms".
We cannot let them get away with this complete change of the narrative, "lessons symptoms". We were told that these vaccines would prevent catching and spreading Covid. I would be remiss to point out that in that same statement, CEO Pfizer did say that the booster would help, so he was acknowledging that which we could all see with our own eyes - the vaccines don't work, only to then push the alleged future efficacy of the boosters.
This shell game is not unlike the one anti-God liberals play with global warming, and evolution. The evidence refutes the narrative, but the solution is always somewhere in the future, or further in the past than we have discovered. Forget that the ice caps were supposed to be gone by 2008, 2010, 2012, 2013, etc. etc. ad nauseam. The oceans are gonna rise, but the liberal elitists pushing this propaganda keep buying ocean front property. I wouldn't put it past 0bama to have pushed this narrative just so he could get a better deal on that ocean front mansion he bought after leaving office.
And as for evolution? The "missing link" is still missing, when reality dictates that we should have found millions of missing links by now. Most people do not understand the basic concept of evolution, that being the transition from one distinct species to a new one. The number of intermediate steps needed is phenomenal once we understand the sheer complexity of even a single cell.
So bad is the evidence that idiots like Dawkins are now saying that everything came from nothing, because they cannot explain what we see. So bad is the evidence for evolution that they want us to believe that an alien race seeded the Earth, another infinitely regressing argument that does anything but answer the question.
